Service for the regionInstanceGroupManagers resource.

https://cloud.google.com/compute/docs/reference/rest/v1/regionInstanceGroupManagers

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

AbandonInstances(std::string const &, std::string const &, std::string const &, google::cloud::cpp::compute::v1::RegionInstanceGroupManagersAbandonInstancesRequest const &, Options)

Flags the specified instances to be immediately removed from the managed instance group.

Abandoning an instance does not delete the instance, but it does remove the instance from any target pools that are applied by the managed instance group. This method reduces the targetSize of the managed instance group by the number of instances that you abandon. This operation is marked as DONE when the action is scheduled even if the instances have not yet been removed from the group. You must separately verify the status of the abandoning action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request. https://cloud.google.com/compute/docs/reference/rest/v1/regionInstanceGroupManagers/abandonInstances

Parameters
Name	Description
project	std::string const & Project ID for this request.
region	std::string const & Name of the region scoping this request.

opts	Options Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
future< StatusOr< google::cloud::cpp::compute::v1::Operation > >	A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a [google.cloud.cpp.compute.v1.Operation] proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

In this case, the proto message is a google.cloud.cpp.compute.region_instance_group_managers.v1.UpdatePerInstanceConfigsRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
opts	Options Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
future< StatusOr< google::cloud::cpp::compute::v1::Operation > >	A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a [google.cloud.cpp.compute.v1.Operation] proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.
